This guide describes key elements for including travel time reliability evaluation within traffic analysis approaches. It includes information on observing the system; defining the problem; collecting and preparing data for analysis; creating the model; verifying, calibrating, and validating; and data processing, analysis, and presentation, as well as some examples.
